Ovarian cysts.. Could it be from IUD??

Hi, I just went to the doctor and had two types of ultrasounds because I couldnt find the strings for my IUD and my doctor couldnt either.. Well in the regular ultrasound my IUD still was not found so had to have the endovaginal (i think thats what its called) but anyway the internal camera.. And my IUD was found in place but an ovarian cyst was found also on the right side..
I have never had one of them before so I am wondering if the IUD could be the cause of it??
I have herd people getting them with it but never knew if it could be a for sure cause.. If so I want it removed because I dont want to be dealing with them all the time.. I have to go back in 2 months to have it checked unless it becomes more of a problem sooner..
So my question is..
Has anyone with an IUD developed a ovarian cyst? Did it take care of itself or did u need surgery? And was the IUD the cause?
Any other info is great as well..
